Optimizing log analysis in saas environments

ABSTRACT

Embodiments of the present invention provide methods, computer program products, and systems for optimizing log analysis, such as in SaaS environments. Embodiments of the present invention can be used to determine an optimal log analysis location and ensure that the log file is processed at the optimal location based, at least in part, on the log file size and available network bandwidth.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of data analytics, and more particularly to data analytics in SaaS environments.

Log analytics refers to the science of interpreting computer generated records known as logs. Logs, in their broadest sense, are a written record of events that are encountered by one or more computing devices in the form of a stream of messages in time-sequence. Logs be used by computing devices for a wide variety of purposes. For example, logs may be used to record events encountered during an installation of software. Other times, logs can record errors in a particular application. System error logs store a record of all the error reports that are received from system components. The error log can then be used by system administrators or maintenance engineers to trace and understand the cause of the error.

Data found on these logs can range from a few hundred megabytes to a few terabytes. Logs can be transmitted by network devices, operating systems, applications, and programmable devices to servers dedicated to analyzing data found in logs. Other times, logs can be written, stored, and analyzed locally on the user's computer after log analysis software has been “pushed” to the user's computer from the server.

SUMMARY

In one embodiment of the present invention, a method is provided comprising: identifying, by one or more computer processors, a log file to be processed; identifying, by one or more computer processors, a file size of the log file and network bandwidth available to transmit log file data from a first computer system to a second computer system; determining, by one or more computer processors, an optimal log analysis location based, at least in part, on the identified file size and the identified network bandwidth; and processing, by one or more computer processors, the identified log file based, at least in part, on the identified optimal log analysis location.

DETAILED DESCRIPTION

Embodiments of the present invention recognize the need to provide more efficient allocation of resources for processing logs. Sometimes, log file sizes can be massive (e.g., a few gigabytes to a few terabytes). Transmitting these logs over a slow network connection to a server dedicated to processing logs can be time consuming and inefficient. Conversely, pushing log analysis software to a local computer to process the log may be an equally inefficient use of resources to analyze a log that is small in size. Embodiments of the present invention provide solutions for determining a log analysis location and ensuring that the log file is processed at the optimal location, based, at least in part, on log file size and network bandwidth. In this manner, as discussed in greater detail later in this specification, embodiments of the present invention can be used to optimize processing of logs.

FIG. 1 is a functional block diagram of a computing environment 100, in accordance with an embodiment of the present invention. Computing environment 100 includes client computer system 102 and server computer system 110, interconnected via network 108. Client computer system 102 and server computer system 110 can be desktop computers, laptop computers, specialized computer servers, or any other computer systems known in the art. In certain embodiments, client computer system 102 and server computer system 110 represent computer systems utilizing clustered computers and components to act as a single pool of seamless resources when accessed through network 108. In certain embodiments, client computer system 102 and server computer system 110 represent virtual machines. In general, client computer system 102 and server computer system 110 are representative of any electronic devices, or combination of electronic devices, capable of executing machine-readable program instructions, as described in greater detail with regard to FIG. 4.

Client computer system 102 includes log analysis program 104 and application 106. Log analysis program 104 receives logs from application 106, and determines the optimal analysis location to process logs based, at least in part, on log file size and network bandwidth. The term “optimal analysis location”, as used herein, refers to a location at which to analyze a log that is determined based on file size of the log and available bandwidth. The optimal analysis location may be an endpoint location where the log was generated, a dedicated log analysis server, or a combination of the endpoint location and dedicated log analysis server. For illustrative purposes, this embodiment may be discussed with respect to client computer system 102 serving as the endpoint location and server computer system 110 serving as the dedicated log analysis server. Responsive to determining that the optimal location to process a log is on client computer system 102, log analysis program 104 can instruct log processor 112 to push log analysis software to client computer system 102 and processes the log accordingly. If log analysis program 104 determines that the optimal location to process a log is on server computer system 110, log analysis program 104 can then transmit the log over network 108 to log processor 112 for processing.

Application 106 monitors one or more components of client computer system 102, generates logs for client computer system 102, and sends the generated logs to log analysis program 104. Application 106 can generate logs responsive to detecting errors in client computer system 102. The term, “logs”, as used herein, refer to generated files that record events that occur in a computer system. For example, an error log is a file containing information for errors that have occurred on one or more computer systems (e.g., error identifiers, timestamps, causes, etc.). A transaction log is a file that contains information for database transactions, such as reads, writes, and deletes, which can allow a database to be recovered after system failure. Application 106 can also receive logs from one or more components of client computer system 102.

Server computer system 110 includes log processor 112. Log processor 112 is an application or service that can read and parse log files to generate readable data. Log processor 112 receives log files from log analysis program 104, analyzes the received log files, and sends the analyzed log files to log analysis program 104. For example, where the received log file is an error log, log processor 112 can parse the log file and, based on values contained in the log file, parses out indicators pertaining to what caused an application to fail. Log processor 112 can also push log analysis software to client computer system 102 responsive to receiving instructions from log analysis program 104.

Network 108 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and include wired, wireless, or fiber optic connections. In general, network 108 can be any combination of connections and protocols that will support communications between client computer system 102, log analysis program 104, application 106, server computer system 110 and log processor 112, in accordance with a desired embodiment of the invention.

FIG. 2 is a flowchart 200 illustrating operational steps for processing a log, in accordance with an embodiment of the present invention.

In step 202, log analysis program 104 receives a log from client computer system 102 generated by application 106. In this embodiment, log analysis program 104 receives a log in the event of a failure of one or more components of client computer system 102. The term, “failure”, as used herein, refers generally to any abnormal termination, interruption, or error in software and/or hardware in the client computer system or another component of the computing environment that affects client computer system 102.

In step 204, log analysis program 104 determines an optimal log analysis location for the received log. In this embodiment, log analysis program 104 determines the optimal log analysis location based, at least in part, on file size of the received log and available network bandwidth to transmit the log file to a server computer system 110 via network 108, as discussed in greater detailed with regard to FIG. 3.

In step 206, log analysis program 104 processes the log, based on the determined optimal log location. For example, if log analysis program 104 determined the optimal log analysis location to be server computer system 110, log analysis program 104 transmits the log to server computer system 110 for processing. If log analysis program 104 determined the optimal log analysis location to be client computer system 102, log analysis program 104 calls log processor 112 to send software to client computer system 102 to enable log analysis program 104 to process the log. If, for example, log analysis program 104 determined the optimal log analysis location to be a combination of client computer system 102 and server computer system 110, log analysis program can divide the log file into two portions (e.g., A and B) for processing. For example, log analysis program 104 can send portion A of the log file to log processer 112 for processing. Log analysis program 104 can further transmit a command to log processor 112 instructing log processor 112 to push log analysis software to client computer system 102. Responsive to receiving log analysis software, log analysis program 104 can then process portion B of the log file locally.

FIG. 3 is a flowchart 300 illustrating operational steps for selecting a log analysis location, in accordance with an embodiment of the present invention. For example, the operational steps of flowchart 300 can be performed at step 204 of flowchart 200.

In step 302, log analysis program 104 identifies the log file size of a received log. For example, the log file size can range from a kilobyte to greater than a gigabyte.

In step 304, log analysis program 104 identifies the current bandwidth (e.g., the amount of data that can be transferred during a second, expressed as bits per second) of one or more connections of network 108 that can be used to transmit log data from client computer system 102 to server computer system 110.

In step 306, log analysis program 104 determines whether the identified bandwidth satisfies a first threshold bandwidth (TBL). In this embodiment, bandwidth less than or equal to 100 kilobytes per second satisfies TBL. In other embodiments, TBL can be configured with any desired bandwidth value that represents a slow transmission speed.

If, in step 306, log analysis program 104 determines that TBL is satisfied, then, in step 308, log analysis program 104 processes the log locally on client computer system 102. In this embodiment, log analysis program 104 processes the log locally by transmitting a command to log processor 112 to push log analysis software to client computer system 102. Responsive to receiving log analysis software, log analysis program 104 executes the software to process the log.

If, in step 306, log analysis program 104 determines that T_(BL) is not satisfied, then, in step 310, log analysis program 104 determines whether the identified bandwidth satisfies a second threshold bandwidth (T_(BM)). In this embodiment, bandwidth greater than T_(BL) but less than 30 megabytes per second satisfies T_(BM). In other embodiments, T_(BM) can be configured with any desired bandwidth value that represents a medium transmission speed.

If, in step 310, log analysis program 104 determines that T_(BM) is satisfied, then, in step 312, log analysis program 104 determines whether the identified size satisfies a first threshold size (T_(FS)). In this embodiment, log file sizes less than or equal to 100 megabytes satisfies T_(FS). In other embodiments, T_(FS) can be configured with any desired file size that represents a small file size.

If, in step 312, log analysis program 104 determines if T_(FS) is satisfied, then, in step 314, log analysis program 104 transmits all logs to log processor 112 via network 108 for processing.

If, in step 312, log analysis program 104 determines that T_(FS) is not satisfied, then in step 316, log analysis program 104 breaks up the log. In this embodiment, log analysis program 104 breaks up the log file by splitting the log file into a first and second portion. For example, log analysis program 104 can split the log file into two equally sized portions. In other embodiments, log analysis program 104 can split the log file into three or more portions of various file sizes.

In step 318, log analysis program 104 processes a portion of the log locally on client computer system 102. In this embodiment, log analysis program 104 processes the first portion of the log locally by transmitting a command to log processor 112 to push log analysis software to client computer system 102. Responsive to receiving log analysis software, log analysis program 104 can execute the software to process the log.

In step 320, log analysis program 104 transmits the remaining portion of the log to log processor 112 on server computer system 110 via network 108 to process the remaining portion of the log. In this embodiment, log analysis program 104 transmits the remaining second portion of the log.

If, in step 310, log analysis program 104 determines that T_(BM) is not satisfied, then, in step 322, log analysis program 104 determines whether the identified size satisfies a second threshold size (T_(FL)). In this embodiment, a log file greater than or equal to one gigabyte satisfies T_(FL). In other embodiments, T_(FL) can be configured with any desired file size that represents a large file size.

If, in step 322, log analysis program 104 determines that T_(FL) is not satisfied, then, in step 324, log analysis program 104 transmits all logs to log processor 112 for processing.

If, in step 322, log analysis program 104 determines that T_(FL) is satisfied, then processing continues at step 316 until completion, as previously discussed.
